Multifocal choroiditis: Indocyanine green angiographic features
The aim of this study is to retrospectively evaluate the indocyanine green (ICG) angiographic features in 13 patients affected by multifocal choroiditis. We identified two clinical and angiographic patterns. The ‘active’ pattern showed hypofluorescence up to the late phases and more extensive choroidal involvement than presumed by ophthalmoscopy and fluorescein angiography. In the ‘inactive’ pattern, ICG angiography showed hypofluorescence during all the phases: no increase in lesion number was observed between early and late phases. Choroidal neovascularization was present in 10 patients, and it was bilateral in 2 of these: it occurred only in the inactive stage. The appearance of choroida…

In Vitro Generation of Pancreatic Endocrine Cells from Human Adult Fibroblast-Like Limbal Stem Cells
Stem cells might provide unlimited supply of transplantable cells for β-cell replacement therapy in diabetes. The human limbus is a highly specialized region hosting a well-recognized population of epithelial stem cells, which sustain the continuous renewal of the cornea, and the recently identified stromal fibroblast-like stem cells (f-LSCs), with apparent broader plasticity. However, the lack of specific molecular markers for the identification of the multipotent limbal subpopulation has so far limited the investigation of their differentiation potential. In this study we show that the human limbus contains uncommitted cells that could be potentially harnessed for the treatment of diabete…
A case-control study on risk factors for nuclear, cortical and posterior subcapsular cataract: The Casteldaccia Eye Study
Purpose: To investigate risk factors for nuclear, cortical and posterior subcapsular age-related cataract. Methods: A case-control study was carried out on subjects aged 40 years and older, living in Casteldaccia, Sicily. Twenty-seven potential risk factors were investigated.

Studio clinico randomizzato e controllato sull'efficacia clinica dell'uso di lenti multifocali refrattive versus diffrattive nella chirurgia della cataratta
OCT is not useful for detection of minimal diabetic retinopathy in type 1 diabetes.
Optical coherence tomography (OCT) has been proven useful in measuring retinal thickness (RT) in patients with diabetes, although with discordant results in different studies. We examined RT in patients with type 1 diabetes (T1D) with or without minimal diabetic retinopathy (MDR) to test whether OCT is able to identify early retinal changes and potential correlations with metabolic parameters. RT of 102 patients with T1D (53 females, 49 males, aged 27.03 +/- 7.4 years) and of 42 healthy controls was examined, with analysis of nine different sectors (fovea, four pericentral and four peripheral sectors). According to the results of basal fundus photography, patients were divided into two grou…
Variations in central corneal thickness during the menstrual cycle in women.
PURPOSE: We report changes in the central corneal thickness during various phases of the menstrual cycle. METHODS: We recruited 16 healthy women of reproductive age and measured the central corneal thickness at 3 points in their menstrual cycle, beginning on days 1 to 3 and again at ovulation and at the end of the cycle (days 27-32). Ovulation was determined with a test that determines the peak of luteinizing hormone in the urine. RESULTS: We found that the central cornea was thinnest at the beginning of the cycle (mean = 536 microm). Corneal thickness increased at ovulation (mean = 549 microm) and at the end of the cycle (mean = 559 microm). The difference in corneal thickness was statisti…

Day care cataract surgery in Central and Southern Italy: a multicentric survey
Abstract Background Cataract day surgery has rapidly gained worldwide acceptance, because the new surgical techniques and costs are generally lower than those involved in ordinary hospitalization. Cataract surgery serves as a proxy indicator of the trend towards day surgery hospitalization in Italy and, therefore, of regional variability in health-care delivery and cost. The aim of this study was to update the diffusion of cataract day surgery through various surgical ophthalmological centers in central and southern Italy during 2005. Methods A two-stage stratified cluster sampling method was used to draw a sample of Cataract Surgery Unit from Ophthalmic Units of central and southern Italy.…
